Additional Info

NOS in this case means that it is not clear if the condition is Mesenteric ischemia, acute or Mesenteric ischemia, chronic.

Ischemic gut guideline

• SMW

• Cargo

• Categories

There are separate codes for different parts of the ischemic gut:

• The following 3 items refer to ischemia of the intestines, including small bowel (including duodenem), or colon, rectum, anus
  • Mesenteric ischemia, acute
  • Mesenteric ischemia, chronic
  • Mesenteric ischemia, NOS
• For ischemia of the stomach -- use Disorder of stomach or duodenum, NOS
• For ischemia of the liver -- use Disorder of liver, NOS
• For ischemia of the esophagus --- use Disorder of esophagus, NOS
• Thus, these various codes variously cover the following concepts:
  • "ischemic bowel"
  • "ischemic gut"
  • "mesenteric arterial thrombosis, embolism or thromboembolism"
  • "mesenteric vein thrombosis, embolism or thromboembolism"
  • "mesenteric arterial atherosclerosis"
• But these codes do NOT include:
  • The cause of that ischemia/infarction. As usual, if the cause is known, link the code for the cause to the relevant code as above for the ischemia, e.g: Atherosclerosis of arteries, NOS, Thrombosis or embolism of artery, NOS, Septic Thrombosis or Embolism, NOS, Disorder of artery/arteries, NOS
  • GI arterial disorders in the absence of mesenteric ischemia/infarction.

Alternate ICD10s to consider coding instead or in addition

• Mesenteric ischemia, acute
• Mesenteric ischemia, chronic
• Duodenitis
• Ulcerative colitis
• Gastrointestinal infection (gastroenteritis), bacterial, NOS
• Gastrointestinal infection (gastroenteritis), viral
• Gastrointestinal infection (gastroenteritis), protozoal, NOS
• Gastrointestinal infection (gastroenteritis, colitis), bug NOS
• Colitis, enteritis, entercolitis, or gastroenteritis, noninfectious NOS
